Microfibres of cellulose were extracted from tara residues (TR), obtained after the production process, and used to remove dyes in aqueous solution. Caesalpinia spinosa (Molina) Kuntze or Tara spinosa, commonly known as tara, is a thorny shrub native to Peru. For these purposes, tara residues (TR) from the production process are used to extract cellulose microfibres (CMF). First, TR are treated in basic mediums; then, they are transferred to an acidic medium. Finally, they are ground in a cutting mill for a short period of time. Scanning electron microscopy was used to characterize CMF. Fibre sizes of approximately 10 μm in length and 300–500 nm in diameter were observed. The crystallinity index calculated from X-ray patterns was defined at 77%. Infrared spectroscopy showed that treating TR with chemical products produces TR delignification. The dye adsorption tests (basic yellow, basic blue 41, basic blue 9 and basic green 4) in water demonstrated that isotherms adjust to the Langmuir model, with maximum respective adsorption values of 43.6, 45.5, 75.0 and 112.2 mg.g⁻¹ for each dye.

从塔拉残渣（TR）中提取纤维素的微纤维，在生产过程后获得，并用于去除水溶液中的染料。刺槐（Molina）昆茨或塔拉刺，俗称塔拉（Tara），是秘鲁的一种棘手灌木。为此，生产过程中的塔拉残渣（TR）用于提取纤维素微纤维（CMF）。首先，TR在基本培养基中处理；然后，将它们转移到酸性介质中。最后，将它们在切割机中磨短时间。扫描电子显微镜用于表征CMF。观察到的纤维长度约为10μm，直径约为300-500 nm。由X射线图案计算出的结晶度指标定义为77％。红外光谱显示，用化学产品处理TR会产生TR去木质素。染料在水中的吸附测试（碱性黄色，碱性蓝色41，碱性蓝色9和碱性绿色4）表明等温线适应Langmuir模型，最大吸附值分别为43.6，每种染料^-1。
